You are progressing; it's just not showing up in the tests yet. It's not unusual to see minimal overall score improvements during the 9-week course. You're tinkering with a bunch of different things and it takes time to pull that all together onto a full test scenario.
Are you taking the real test for the first time just as a trial run, so that you can see what the test center is like, acclimate to the environment, etc? If so, that's a fine idea.
If you're thinking that somehow your score is going to jump big next week and you might not have to take the test a second time... then you should consider cancelling or postponing next week's test. That would just be putting pressure on yourself to achieve something that's very unlikely, and that will likely kill your confidence / morale for some period of time.
At the end of your program, you'll be able to sign up for something called a PCA (post course assessment). This is a 30-min phone call with an instructor to take about a post-course study plan. The instructor will have looked at your practice exams before coming to the meeting. Make sure you sign up for this.
Next, it sounds like mental fatigue issues are affecting your verbal performance. If your performance drops at the end, that will bring your scoring level down. (On this test, where you end is what you get.)
Read this for ideas about how to help manage / reduce mental fatigue:

Have you been doing the essay and IR on your practice tests? How much have you prepared for those two sections? Obviously, we don't care so much about those scores, but we do care about how they might mentally fatigue us before we can get to quant and verbal.
For the essay, read this and do what it says:
http://www.manhattangmat.com/blog/index ... no-thanks/For IR, study the 4 question types enough that you know what you're supposed to do with each of them. Also, know which kinds of questions are your least favorite / worst. **Skip 1 to 3 of those immediately (random guesses) and spend your time on the other ones that you like better. **Note: I'm suggesting this now because the schools don't care as much about IR right now. If someone reading this in the future wants to do the same thing, you first need to check to see how the landscape may have changed with respect to the importance of IR.
The biggest thing I think you need to do / decide right now: are you sure you want to take the test next week? If you can really view it as a dry run, strictly practice, performance doesn't actually matter because it's not your "real" test (that'll come later), then that's fine. But if you think that it's going to hurt your morale and motivation... then consider giving yourself some additional time. Don't go into it all stressed out and placing crazy pressure on yourself - that's a recipe for a disappointing test experience.
Let me know what you decide!
